    摘要: A method and apparatus for the nickel-plating of components, in which the finished component, which is to be nickel-plated, is heated to a temperature between 150.degree. and 200.degree. C. and is at the same time subjected to a continuously flowing gas stream containing nickeltetracarbonyl (Ni(CO).sub.4) and an entrainment gas. In this procedure nickel is constantly desposited from the gas phase on the heated surface from the gas stream which continuously flows around the finished component and consists of an entrainment gas and nickeltetracarbonyl. The nickel coating produced by this procedure adheres well, given normal pre-cleaning, and is practically seal-tight even in very thin coating thicknesses (0.1-1.mu.).

    摘要: An invention involving a process and apparatus for isotope-separation applications such as uranium-isotope enrichment is disclosed which employs cascades of gas centrifuges. A preferred apparatus relates to an isotope-enrichment unit which includes a first group of cascades of gas centrifuges and an auxiliary cascade. Each cascade has an input, a light-fraction output, and a heavy-fraction output for separating a gaseous-mixture feed including a compound of a light nuclear isotope and a compound of a heavy nuclear isotope into light and heavy fractions respectively enriched and depleted in the light isotope. The cascades of the first group have at least one enriching stage and at least one stripping stage. An example of such a gaseous mixture is uranium hexafluoride incorporating uranium-235 and uranium-238. The unit further includes means for introducing a gaseous-mixture feedstock into each input of the first group of cascades, means for withdrawing at least a portion of a product fraction from the light-fraction outputs of the first group of cascades, and means for withdrawing at least a portion of a waste fraction from the heavy-fraction outputs of the first group of cascades. The isotope-enrichment unit also includes a means for conveying a gaseous-mixture from a light-fraction output of a first cascade included in the first group to the input of the auxiliary cascade so that at least a portion of a light gaseous-mixture fraction produced by the first group of cascades is further separated into a light and a heavy fraction by the auxiliary cascade. At least a portion of a product fraction is withdrawn from the light fraction output of the auxiliary cascade. If the light-fraction output of the first cascade and the heavy-fraction output of the auxiliary cascade are reciprocal outputs, the concentration of the light isotope in the heavy fraction produced by the auxiliary cascade essentially equals the concentration of the light isotope in the gaseous-mixture feedstock.

    摘要: The invention is an improved form of an ultracentrifuge used in the separation of gases, particularly those of high molecular weight. Through the introduction of an inner cylinder within the outer cylinder of a high speed centrifuge, a higher over-all flow profile efficiency is created. In addition, although a gain of lesser significance, the vacuum core present in ultra centrifuges, which does not contribute to the separative power of the centrifuge, is virtually eliminated. Moreover, for those gases in which the maximum pressure in the centrifuge is limited by a phase change, i.e. the maximum pressure in the centrifuge must be kept below the vapor pressure, the addition of the inner cylinder raises the pressure in the central core region by several orders of magnitude, which permits the subsequent reduction of pressure on the outer walls of both inner and outer cylinders without any portion of the centrifuge being in the Knudsen regime. With this reduction of pressure on the outer walls, the gas can then be centrifuged at a lower temperature, thus further increasing the productive capacity of such a device.

    摘要: A centrifuge, for separating a fluid feed into two fluids, includes a rotor shaft and a rotor housing within which is a set of concentric, equal spaced cylindrical shells providing elongated annular chambers for parallel flows of fluid. Distributor means extends radially from the shaft within one end housing portion to furnish fluid separately to the chambers. One collector means to receive one separated fluid extends radially from the shaft within the other end housing portion to communicate with the chambers. A second collector means is located preferably at the same transverse plane passing through the shaft by using radially extending walls within that end portion of the housing to divide it into a number of pie-shaped chambers, each having an outlet adjacent the shaft. Each collector means includes some of these pie-shaped chambers. In the broadest construction the total area of a set of openings of the distributor means (or of one of the collector means when appropriate) communicating with a specific annular chamber is proportional to a value between about the third power and about the fourth power of the average radius of the annular chamber. There are outlet pipes communicating with the two collector means and one of the pipes is valved to control the volume ratio of removed fluids.

    摘要: A method of and a device for de-aerating greases, in which the grease to be de-aerated is fed to the inner side of a cylindrical drum which rotates at a high speed. The grease feed rate is continuous and so high that the grease flows along the inner side of the drum in a thin layer, meanwhile discharging air present therein. The thin layer is collected again at some distance from the grease inlet in a stationary duct which extends outside the drum.
